Nhwɛso ahorow

Saa adesua ahorow yi ho nhwɛso ahorow bi a egyina hɔ ma ni:

Horizontal a wɔde hyɛ mfinimfini

Bio nso, Bootstrap nso de .mx-autoadesuakuw bi a wɔde hyɛ mfinimfini a ɛkɔ soro a ɛwɔ fixed-width block level content —kyerɛ sɛ, nsɛm a ɛwɔ display: blockne widthset bi —denam horizontal margins a wɔde besi auto.

Element a ɛwɔ mfinimfini

<div class="mx-auto" style="width: 200px;">
  Centered element

Negative margin

Wɔ CSS mu no, marginagyapade betumi de botae ahorow a enye adi dwuma ( paddingntumi). Saa negative margins yi yɛ nea wɔagyae no default so , nanso wobetumi ama ayɛ adwuma wɔ Sass mu denam nhyehyɛe so $enable-negative-margins: true.

Ɛkame ayɛ sɛ syntax no ne default, positive margin utilities no yɛ pɛ, nanso wɔde aka ho nansa na wɔabisa no kɛse. Nhwɛso adesuakuw bi a ɛne .mt-1:

.mt-n1 {
  margin-top: -0.25rem !important;

Kwan

Sɛ wode redi dwuma display: grida, wubetumi de gaputilities adi dwuma wɔ ɔwofo grid container no so. Eyi betumi akora sika so wɔ hia a ɛsɛ sɛ wode margin utilities ka grid nneɛma ankorankoro ho (mmofra a wɔwɔ display: gridcontainer bi mu). Gap utilities no yɛ mmuaeɛ default so, na ɛnam yɛn utilities API so na ɛyɛ, a egyina $spacersSass map no so.

Grid adeɛ 1

Grid adeɛ 2

Grid adeɛ 3

<div class="d-grid gap-3">

  <div class="p-2 bg-light border">Grid item 2</div>
  <div class="p-2 bg-light border">Grid item 3</div>
</div>

Mmoa no ka ho ne mmuaeɛ akwan a wɔfa so paw Bootstrap grid breakpoints nyinaa, ne akɛseɛ asia a ɛfiri $spacersmap no mu ( 0– 5). utility class biara nni hɔ .gap-autosɛnea ɛyɛ ade koro no ara wɔ ɔkwan a etu mpɔn so ne .gap-0.
